Commentary:
In 1995 Leica introduced the GPS 300 System. It enabled high-precision positioning with real-time surveying, allowing one to receive precise coordinates while still in the field.
The above image shows components of the System. From top left clockwise: Receiver, Sensor, Controller and external antenna.
The receiver is set up over the control point. The sensor receives the satellite signals from the receiver. The controller controls the sensor, logs the data and manages the survey operation. The “E” designation in a receiver means that it also had an external antenna.
The Society has several components of the 300 System:
ALSA 2010.12.01. Leica Receiver SR 299E (2 units)
ALSA 2010.12.02. Leica Receiver SR 399 (2 units)
ALSA 2010.12.04. Leica (external) Antenna AT 201 (4 units)
ALSA 2010.12.05. Wild (external) Antenna AT 202 (2 units)
ALSA 2010.12.07. Leica Sensor SR 9400 (4 units)
ALSA 2010.12.08. Leica Controller CR 244 (2 units)
